Case ReportsResponse to PD-1 Blockade in Microsatellite Stable Metastatic Colorectal Cancer Harboring a POLE Mutation.
Recent clinical evidence has demonstrated that microsatellite instability (MSI) or defective mismatch repair (MMR) and high tumor mutational load can predict response to the programmed cell death 1 (PD-1) receptor inhibitor pembrolizumab in metastatic colorectal cancer (mCRC). Mutations in polymerase ε (POLE), a DNA polymerase involved in DNA replication and repair, contribute to an ultramutated but microsatellite stable (MSS) phenotype in colorectal tumors that is uniquely distinct from MSI tumors. ⋯ On tumor immunostaining, a large amount of CD8-positive tumor infiltrating lymphocytes (TILs) were present, with >90% of these expressing PD-1. More than 99% of PD-L1 expression was identified on nontumor cells in the tumor microenvironment that were close to the PD-1-positive CD8 TILs. mCRC tumors harboring POLE mutations represent a hypermutated phenotype that may predict response to anti-PD-1 therapy.

Vulvar cancer is a rare malignancy with high curability in early-stage disease, yet poor outcomes for advanced-stage and recurrent disease. Surgical management is at the cornerstone of treatment for most vulvar cancers, and includes conservative and radical resection of the primary vulvar tumor and excision of local lymph nodes, which are major prognostic factors and drive adjuvant treatment. This review summarizes the surgical management of primary squamous cell carcinoma of the vulva, specifically initial treatment guidelines by stage, based on the 2017 NCCN Clinical Practice Guidelines in Oncology for Vulvar Cancer.

Comparative StudyNeoadjuvant Therapy for Rectal Cancer Affects Lymph Node Yield and Status Without Clear Implications on Outcome: The Case for Eliminating a Metric and Using Preoperative Staging to Guide Therapy.
Nodal status has long been considered pivotal to oncologic care, staging, and management. This has resulted in the establishment of rudimentary metrics regarding adequate lymph node yield in colon and rectal cancers for accurate cancer staging. In the era of neoadjuvant treatment, the implications of lymph node yield and status on patient outcomes remains unclear. ⋯ This analysis reiterates that nodal yield in rectal cancer is multifactorial, with neoadjuvant therapy being a significant factor. Node yield and status were not significant predictors of overall survival. A nodal metric may not be clinically relevant in the era of neoadjuvant therapy, and guidelines for perioperative therapy may need reconsideration.

Emerging Issues and Opportunities in Health Information Technology.
When used effectively, health information technology (HIT) can transform clinical care and contribute to new research discoveries. Despite advances in HIT and increased electronic health record adoption, many challenges to optimal use, interoperability, and data sharing exist. Data standardization across systems is limited, and scanned medical note documents result in unstructured data that make reporting on quality measures for reimbursement burdensome. ⋯ In June 2016, NCCN hosted the Emerging Issues and Opportunities in Health Information Technology Policy Summit. The summit addressed challenges, issues, and opportunities in HIT as they relate to cancer care. Keynote presentations and panelists discussed moving beyond Meaningful Use, HIT readiness to support and report on quality care, the role of HIT in precision medicine, the role of HIT in the National Cancer Moonshot initiative, and leveraging HIT to improve quality of clinical care.

Care and Outcomes of Patients With Cancer Admitted to the Hospital on Weekends and Holidays: A Retrospective Cohort Study.
Patients admitted to the hospital on weekends experience worse outcomes than those admitted on weekdays. Patients with cancer may be especially vulnerable to the effects of weekend care. Our objective was to compare the care and outcomes of patients with cancer admitted urgently to the hospital on weekends and holidays versus those of patients with cancer admitted at other times. ⋯ Patients with cancer admitted to the hospital on weekends/holidays experience higher mortality relative to patients admitted on weekdays. This may result from different care processes for weekend/holiday patients, including delayed procedures. Future research is needed to identify key outcome-driving procedures, and ensure timely access to these on all days of the week.
